List-I shows various functional dependencies of energy (E) on the atomic number (Z) . Energies associated with certain phenomena are given in List-II. the option that describes the correct match between the entries in List-I to those in List-II. List-I List-II (P) E Z^2 (1) energy of characteristic x-rays (Q) E (Z-1)^2 (2) electrostatic part of the nuclear binding energy for stable nuclei with mass numbers in the ran

Step-by-step solution

(P) Energy of H -like atom is aligned & E =-13.6 Z ^2 n ^2 So & E Z ^2 & P (5) aligned (Q) Energy of characteristic X-ray by moseley's correction aligned & E=-13.6(Z-1)^2 [ 1 n₁^2 - 1 n₂^2 ] So & E (Z-1)^2 & Q (1) aligned (R) Electrostatics binding energy is proportional to Z(Z-1)R (2) (S) For stable nuclei with mass no. in range 30 to 170 . Binding energy per nucleon is constant & graph is straight line S (4) Ans. (C) is correct
